Fruit flies (Diptera: Tephtritidae) are one of the most important insect pests to fruits worldwide. In Uganda, fruit flies have inflicted considerable yield losses especially in mangos (Mangiferaindica L.), However, there has been no recent assessment of the associated economic damage impact despite the outcries from the farming communities.

The objective of this study was to assess fruit fly prevalence and infestation in mango and other hosts, to guide the development and improvement of fruit fly control measures in the mango industry in Uganda. A survey was conducted in the major mango producing areas of the country.

Intensification of aquaculture production in Uganda is likely to result into disease out-breaks leading to economic losses to commercial fish farms and associated natural aquatic ecosystems.
This survey assessed health profiles of selected commercial fish farms and adjacent natural aquatic ecosystemsto identify fish diseases and parasites affecting Nile tilapia (Oreochroms
niloticus) and African catfish (Clarias gariepinus) in aquaculture systems in Uganda. Fish farms encounter disease out-breaks that cause low survival rates (0 - 30%), especially catfish hatcheries.

Health management issues are not well understood by fish farmers, with some unable to detect diseased fish. Current control strategies to control aquatic pathogens include use of chemotherapeutants and antibiotics.

Potato yields in Uganda have remained low at 7.5 t ha-1. This low yield is attributed to low yielding varieties, poor management practices and lack of quality seed potatoes among other factors. This study was conducted to ascertain the challenges and opportunities of quality seed potato availability and production in the southwestern highlands agro-ecological zone (SWHAEZ).

A total of 15 farmer groups were randomly selected from a sample size of 200 farmers and individually interviewed. The results of study indicated that high transaction costs (43.5%), lack of clear seed delivery system (40.5%) and limited information on the source of seed (14.0%) were the main constraints limiting farmers' access to and use of quality seed potato.

The common dry bean (Phaseolus vulgaris L.) is the most widely grown food legume in Uganda,however, its production in western Uganda has been thr eatened by the bean root rot diseases. Resistant varieties and integrated soil and crop management package for the bean root rot disease,developed by the National Beans Research Programme, were promoted from 2003 to 2007 in Bushenyi and Kisoro Districts that were most susceptible to this disease.

This study was conducted to assess the level of uptake of technologies and practices promoted in the target area, and factors influencing the decision to adopt. Data were collected using a semi-structured questionnaire that was administered to 160 purposively selected bean farmers. The Poisson regression model was used to determine the factors influencing the number of technologies and practices used.

The demand for rice Oryza sativa in Uganda has exceeded local supply resulting into importation of several other rice varieties and brands to meet the deficit. Lack of information on consumer preferences hinders decision-making to invest in the rice sub sector. This study seeks to pr ovide information on consumer preferences of most rice brands and varieties on the local market.

Aconsumer survey and sensory analysis were undertaken in the study. The rice consumers' survey was conducted among 475 households from 8 selected rice growing districts in Uganda using astructured questionnaire to establish culinary attributes of rice preferred. Sensory analysis was conducted by a 25-person controlled sensory panel that evaluated 17 boiled varieties and brands of rice using a hedonic scale of 1-7, to rank basic culinary attributes. Consumers' survey revealed that 27 % of households consumed rice among the starchy food types.
